We're sorry. QuickBooks encountered a problem. Error codes: (-6000, -77).
Intuit recommends several solutions for this problem. The first solution may solve your problem, or you may need to try all of them to resolve the issue. For best results, perform the solutions in the order shown.

.ND and .TLG files are configuration files that allow QuickBooks to access the company file(s) in a network or in multi user mode. Corrupted or damaged .ND or .TLG files can cause errors when opening QuickBooks. Renaming these files will not cause data loss since they are automatically recreated when you scan your company files using the QuickBooks Database Server Manager or open the company file.
